Category Introduction
The Sea Water RO Membrane series is suitable for desalination and deep treatment of seawater and high-concentration brackish water.
Delivering ultra-high salt rejection rates, they deliver optimal long-term economic performance for desalination systems.
The optimized 34-mil inlet flow channel reduces pressure drop and enhances the membrane element's resistance to fouling and cleaning.
They are widely used in seawater desalination, high-concentration brackish water desalination, boiler feed water, papermaking, textile printing and dyeing, and material concentration.
